3 Claims. (01. 198-23) This invention relates to package conveyingmechanism and to the method of conveying packages.

' An important object of the present invention resides in the provisionof new and improved means for feeding articles in a novel manner from aplurality of separate conveyors and depositing the articles on anothersingle conveyor.

Another bbject of the invention is the provision of conveying mechanismfor feeding articles from a plurality of conveyors alternately to aseparate conveyor which is angularly positioned with respect to theother conveyors.

Another object is the provision of conveying mechanism for feedingarticles successively to a rapidly moving conveyor from a plurality ofslower moving conveyors which are angularly disposed with respect to therapidly moving con-.

veyor, the articles from the slower conveyors being fed alternately tothe rapidly moving conveyor.

A further object of the invention consists in the provision of new andnovel mechanism for shifting or feeding articles alternately from slowconveyors to a fast conveyor which is angularly positioned with respectto the slower conveyors, the articles being spaced an appreciabledistance apart on the fast conveyor and then arranged in close proximityon a receiving conveyor to be cartoned or otherwise packaged.

A still further object of the invention is the provision of improvedmeans, properly correlated and synchronized with respect to certainoperable mechanism, for assuring articles fed by slow moving conveyorsto be shifted at the proper time from a predetermined position on theslow conveyors to a predetermined position on a fast moving conveyor. 7

Another object is to provide article feeding and conveying mechanismwith novel operating mechanism which is correlated and synchronizedproperly to provide proper timing of the various parts and to insureproper speeds of the conve-ying parts to. permit continuous operation.

Still another object resides in providing new transferring devices withvariable speeds so that articles from slow moving feed conveyors will bemoved first slowly from the. feed conveyors and thenspeeded during aportion of transfer travel until the. articles are in juxtaposition withrespect to a faster moving angularly disposed conveyor when the. speedis again reduced to insure the articles. being positioned properly onthe faster conveyor;

Still, another object is an improved method of 4. and 6.

2 removing articles from a plurality of conveyors and then feeding thearticles in a new and novel manner to a faster moving conveyor and in aproper sequence.

Numerous other vobjects and advantages will be apparent throughout theprogress of'the specification which follows. Y

Fig. 6 is a detail vertical sectional view on the line 6-6 of Fig. 1,and- .Figs. 7 to 12 are diagrammatic views showing the manner in whicharticles are deposited alternately and successively on the main conveyorfrom a plurality of feed conveyors.

The particular construction herein shown for the purpose of illustratingthe invention comprises a main frame or supporting structure I whichincludes spaced transverse bars 2 con'- nected to upright members oruprights 3, Figs; and 2. Longitudinal plate supporting members 4 arecarried by the upright members 3, and assists in supporting a verticallydisposed plate or other structural member 5, Figs. 2 and 3. A flathorizontal platform in the form of a top plate or table 6, is supportedsuitably and properly on the supporting structure I, preferably by.being supported principally by the uprights 3, Figs. 1

Article conveyor A conveyor drive chain 1, Fig. 2, is driven ty a drivesprocket (not shown) and drives a sprocket 8 on a drive shaft 9, whichis suitably mounted. in proper bearings carried by the main frame I. Agear m, Figs. 2 and 3', fixed rigidly to the sprocket 8, has meshingengagement with an idler gear H which meshes with and drives anotheridler gear I 2'. The idler gear [2 drives a driver gear E3 to which adriving sprocket H! is attached rigidly. A conveyor chain l5, which istrained over the sprocket My and over an. idle sprocket l6, Fig. 2,. isdriven by the drive sprocket 4. A conveyor: support H is arrangedbetween the upper and lower reaches of the conveyor chain l5 andsupports the chain intermediate the sprockets l4 and I6 as shown clearlyin Fig. 2. The sprocket chain |5 carries a plurality of equally spacedlugs l8 which extend downwardly from the lower reach of the chain andengage successive articles to be conveyed along a given path todischarge position, Figs. 1 and 2, the articles being conveyed to themachine by a plurality of angularly spaced feed conveyors l9 and 20,Figs. 1 and 6.

Feed conveyors 19 and 20 The conveyors I6 and 20, Figs. 1, 4, and 6 areendless belts upon which articles A are fed to the machine. The articlesA are placed on the conveyor belts I9 and 20 in any convenient manner,such as by being placed thereon by hand. The endless belt of theconveyor I9, Fig. 4, passes over spaced upper pulleys 2| (only one ofwhich is shown) which are identical with upper spaced pulleys 36 for thebelt 20, Fig. 6; the conveyor belt |9 also passes over a lower drivepulley 22 which is mounted on a drive shaft 23. The shaft 23 carries agear 2-4 which meshes with a gear 25 on a belt tightener pulley 26, overwhich the belt I9 is trained.

The drive gear 24 fixed to the shaft 23 meshes with a gear 21 which isfixed to a drive shaft 28, Fig. 4. The shaft 28v has a bevel gear 29,fixed thereto, which meshes with a gear 30, on a drive shaft 3|, Figs.4, 5 and 6.

The endless conveyor 20 is driven by the lower drive pulley 32, Figs. 4and 6, which is mounted on the lower shaft 23. The gear 33 meshes with agear 34 on a belt tightener pulley 35. The belt 20 trains over the upperspaced pulleys 36.

The feed conveyors l9 and 20 are. driven in an identical manner byseparate identical means and are operated at the same rate of speed tofeed articles A to the article receiving plate 6, Figs. 1, 2, 4 and 6.

The shaft 3|, Figs. 4 to 6, carries a bevel gear 31 which meshes with abevel gear 38. The gear 33 is fixed on a main drive shaft 39 which isoperated in any convenient manner, such as by a motor (not shown), or bybeing connected and driven from another drive shaft. The shaft 39,however, is the main drive shaft for the conveyors l9 and 20, as well asfor certain other operating parts of the mechanism of the invention.

Belt supports 40, Fig. 6, are arranged beneath the upper horizontal flatparts of the conveyor belts l9 and 26 to support the belts so as toprovide a proper flat surface for' the articles which are fed by theseconveyors to the top plate or table 6. Guides 4| and 42 respectively,Fig. 1, are arranged on each side of the conveyors I9 and 20 to guidearticles being fed by the conveyors and transferred by the transferwheels and 46. The left hand guides 4| cooperate and are coextensivewith curved left hand guides 43 and 44 fixed to the top of the plate ortable 6. The guides 43 and 44 each terminate in relative straight partsor pieces which are perpendicular, or substantially perpendicular to theconveyor l5. The conveyors l9 and 20 deliver the articles to the plate 6where they are picked up by transfer wheels 45 and 46 respectively anddelivered to the conveyor I5.

Transfer wheels 45 and. 46

The right hand transfer wheel 46 is mounted at the upper end of avertical shaft 41 which is properly and suitably journalled in bearingscarried by the frame, Figs. 2, 5 and 6. A gear 48 is secured to theshaft 41 and meshes with a gear 49 mounted on a stud 50. A plate 5| isfixed to the gear 49 on the stud 50, the plate 5| carrying a stud 52 ator near its periphery and rotatively supports a roller 53, Fig. 5. Theroller 53 is adapted to be received in the slot of a guideway 54, whichis mounted on, and carried by, a gear 55, the gear 55 being mounted on astud or shaft 56. The roller 53 in the slot of the guide way 54 givesvariable speed to the transfer wheel 46. The gear 55 meshes with a gear51 rotatively mounted on a shaft 58 which also carries a bevel gear 59.The bevel gear 59 meshes with a bevel gear 63 on the shaft 3|. Thetransfer wheel 46 is given variable speed, being rotated by the shaft 3|through the gearing just described. The operation of the transfer wheel46 is such that the wheel 46, while rotating continuously, will havevariable speeds, slowing down at the time an article from the feedconveyor 20 is first picked up and then increasing in speed until thearticle is near the conveyor |5, at which time the rotative speed of thewheel 46 will again recede. The alternate slowing down of the wheel 46,during the picking up and discharging points, maintains the article inproper position and prevents it from shifting during the conveyingoperation, while the speeding up between receiving and dischargingpositions permits for fast operation in transferring. The slowing downand the accelerating of the speed of the wheel 46 is accomplished bymeans of the roller guideway connection 53, 54. The wheel 46, beingdriven from the same driving means which drive the feed conveyors l9 and20 and in proper synchronization therewith, therefore, operates inproper timed relation. The drive for the feed conveyors l9 and 20 andthe wheel 46 is correlated with the drive of the conveyor I5 andoperates in proper timed relation therewith.

The transfer wheel 45 is driven from the same drive shaft 58, Fig. 5,which drives the transfer wheel 46 and therefore operates synchronouslywith the said wheel 46. The wheel 45 is mounted on a vertical shaft 6|which carries a gear 62 meshing with a gear 63, mounted on a stud 64.The gear 63 has a plate 65 fixed thereto, and this plate 65, like theplate 5|, carries a stud 66 upon which a roller 61 is mounted. A slottedguideway 68 is mounted on a gear 69 and receives the roller 61 to givevariable speed to the wheel 45 in the same manner in which variablespeed is transmitted to the transfer wheel 46. The gear 69, which ismounted on a stud I0, meshes with the gear 51 on the drive shaft 58, theshaft 56 being driven from the shaft 3| by the gears 59 and 66,previously described with respect to the wheel 46. The variable speed ofthe transfer wheel 45 is the same as the variable speed of the transferWheel 46 and for the same purposes and reasons. The slow speed of thewheel 45, however, occurs during the faster or accelerated speed of thewheel 46 because the transferring operation of the wheel 45 alternateswith the transferring operation of wheel 46, so as to permit articles tobe delivered properly and alternately from the conveyors |9 and 20. Thearrangement and construction is such that an article is firsttransferred by the wheel 45 from the speed conveyor l3 and then anarticle from the conveyor 20 is transferred from the conveyor 20 by thewheel 46 to the conveyor |5 alternately, the articles being receivedsuccessively by the conveyor I5.

The articles from the conveyors l9 and 20 are held in a position andthen released at a particular proper time. A. holding-releasing; meanspermits the article ready to. be transferred. from binding with thesuccessive articles. on the feed conveyors; particularly should thearticles be sticky or tacky, such as pressed mince meat for which theinvention is particularly applicable. There is a releasable holder H forthe conveyor I9, and a second releasable holder 12 for the conveyor 20.

Releasable holders 71 and 72 the time of its release, causes onearticle. to be broken or released from the next succeeding article, acondition which is desirable, particularly where the articles are of asticky or tacky nature, such as, pressed mince meat.

The arm 13 passes through the conveyor support ll and is operativelysupported by a collar 15. The inner end of the bar 73 is in the form of'a link and is pivotally connected at 16 to the upper arm ll of a camlever 18, which is pivoted at "19 to a part of the machine frame. The

lower arm 39 of the cam lever 78 carries a roller 81 mounted on a stud82 on the arm 80 of the cam lever 18. The roller 8| operates in a camgroove 83, formed in a barrel cam as, which is mounted on the main driveshaft 3|. The cam groove 83 of the cam 84 is a continuous one and hastwo opposed sections, each of which are duplicates, so that duringrotation of the cam 84, the cam lever 78 will be oscillated about thepivot l9 and cause horizontal reciprocation of the bar" 72. Therefore,during the reciprocatory movement of the bar l3, the holding end or armit will be moved away from the articles on the conveyor 26 atpredetermined timed intervals.

The mechanism for operating the holder H for the feed conveyor is isidentical with the mechanism for operating the holder 12. The

holder ll includes an elongated forwardly extending bar 85, which issupported by a collar. This bar 85 terminates at its inner end into areleasable bent end or'arm 88. adapted to be arranged in front of thefirst article on the feed conveyor [9 and then is released at apredetermined timed interval so as to permit the transfer wheel 65 totransfer the article from the conveyor l9 to the conveyor 5. The. bar 85is pivotally connected at 86 to the upper arm 87 of a second cam. lever88, which, like the cam lever 18, also ispivoted at it to the frame. Thelower arm 89 of the cam lever 88 carries a stud 90 upon which a roller9! is revolubly mounted. The roller 9| is adapted to engage the groove83 in the cam 84 at a point spaced one hundred eighty degrees from thepoint where the roller BI is received in the groove 83. The cam groove83, therefore, causes operation of the rod or arm 85 in identically thesame manner in which the cam groove causes operation of the bar 73. Thecam groove 83 is so constructed that when the holder 1! is in holdingposition, the holder 13 will be The arm 35 is in released position. Theholders H1 and 12, therefore, move to holding and releasing positionalternately because the transfer wheels 45 and 36 transfer articlesalternately from these transfer wheels to the conveyor IS. Thearrangement and construction is such thatv an article is firsttransferred from the feed conveyor [9 by the wheel 45 and then anarticle from the conveyor is transferred by the transfer wheel 46 to bedeposited on the conveyor I5. The wheels 45 and. 46, while operatingcontinuously, will cause articles to be placed successively in. theconveyor I5 from the feed conveyors l9 and 2t alternately.

The transfer wheels 45 and as are provided with radially extending arms,the transfer wheel 4.5. having outwardly extending arms or. fingers 92and 93, which are spaced one hundred eighty degrees. apart. The transferwheel 46 isprovided with outwardly extending arms or fingers 3d and 9.5which, like the fingers 92 and 93, are spaced one hundred eighty degreesapart. The fingers 92 and 93 of the transfer wheel 45 are positioned atright angles or perpendicular with respect to the fingers 94 and 95 ofthe transfer wheel 46. An article on a conveyor I9 is adapted to beengaged by finger 92 on the transfer wheel 45, and then positionedproperly in a space between lugs E3 on the conveyor chain [5. An articleon the conveyor 20 is then adapted to be engaged by the finger 95 on thetransfer wheel 46 and positioned properly in a space be.- tween the saidlugs on the conveyor Ill. The continuing rotation of the transfer wheels45 and 56, therefore, cause articles to be transferred alternately bythe fingers 92, 94, 93 and 95 from the conveyors l9 and 20 respectivelyand placed successively in the spaces between lugs of the conveyor l5where they are carried to the packaging conveyor chain 1.

The manner in which the articles from the conveyors l9 and 2e aretransferred alternately from the conveyors I5 and 2!! and placedsuccessively in the conveyor l5 for engagement with the lugs l3 is showndiagrammatically in Figs. 7 to 12 inclusive.

Operation The transfer wheels 55 and 15, Figs. 7 to 12, each revolvesimultaneously and continuously and in a clockwise direction. Thefingers S2 and '93 on the transfer wheel are spaced one hundred eightydegrees apart and extend radially outward therefrom. The fingers 92 andas form a part of this transfer wheel at and are preferably formedintegrally therewith. The fingers S 3 and 95 on the transfer wheel asare also spaced one hundred eighty degrees apart, extend radiallyoutward from the transfer wheel 46, and are preferably formed integrallywith this transfer .wheel. The finger as is positioned on the peripheryof the transfer Wheel and is ninety degrees ahead of the positioning ofthe finger 95 onthe periphery of the transfer wheel 56. The conveyorchain It moves to the right in a plane parallel to a line drawn throughthe centers of shafts 6: and All. The lugs 23, which are lettered athrough 9! for the purpose of describing the mode of operation, arefastened transversely to the conveyor chain 15 and extend downwardlyfrom the lower reach of said conveyor chain l5. Between the instants oftime represented by each successive view from Fig. '7 through Fig. 12,each lug Is on the conveyor chain advances a distance equal to one-halfthe distance between the centers of the shafts SI and 41.

At the beginning of the operation, the machine being empty and ready foroperation and the feed conveyors I9 and 20 being loaded with articles A,the machine transfers articles alternately from the conveyors I9 and 20to the conveyor I5. For the purpose of describing the operation of themachine, the articles A fed by the conveyor I9 are numbered 1, 3, 5, '7,etc. and articles on the feed conveyor 20 are numbered 2, 4, 6, 8, etc.The transfer wheel 45 picks up successively articles 1, 3, 5, 7, etc.from the feed conveyor I9; similarly, the transfer wheel 46 will pick upsuccessively the articles 2, 4, 6, 8, etc. from the conveyor 20. Theoperation of the machine will result in article 1 being first placedupon the conveyor chain I5, succeeded by article 2, whereupon article 3will follow, and so on.

The finger 92 of transfer wheel 45 will first pick up article 1 on thefeed conveyor I9, as shown in Fig. '7. The finger 94'on transfer wheel46 will next pick up article 2 on the feed conveyor 29, as shown in Fig.8, while article 1 from the feed conveyor I9 is being swung through anarc toward the conveyor chain I5, being guided by guides 4I-44 duringthe transfer movement. The finger 92 on transfer wheel 45 will thenplace article 1 before lug I8b, said lug lBb now having been moved to aposition in a plane radial to transfer wheel 45, as shown in Fig. 9.Simultaneously, article 2 from the feed conveyor 20 will be swungthrough an arc toward the conveyor chain I by the finger 94 of transferwheel 46, said'article 2 being guided by guides 4I44; the finger 93 oftransfer wheel 45 will then pick up article 3 from the feed conveyor I9.As a succeeding step, the finger 94 of transfer wheel 46 will placearticle 2 before lug I8a, said lug IBa having moved to a position in aplane radial to transfer wheel 46; also, the finger 95 of transfer wheel46 will pick up article 4 from the feed conveyor 20 while finger 93 oftransfer wheel 45 swings article 3 through an are from the feed conveyorI9 toward the conveyor chain I5, as shown in Fig. 10. As a next step,the finger 93 of the transfer wheel 45 will place article 3 before thelug I8d, said lug I8d now having been moved to a position in a planeradial to transfer wheel 45; the finger 92 of transfer wheel 45 willpick up article 5 from the feed conveyor I9; and article 4 from the feedconveyor 20 will be swung through an arc toward the conveyor chain I5,as shown in Fig. 11. The finger 95 of the transfer wheel 46 will thenplace article 4 from feed conveyor 20 before lug I80, said lug I80 nowhaving been moved to a position in a plane radial to transfer wheel 46;the finger 94 of transfer wheel 46 will pick up article 6 on feedconveyor 29 and the finger 92 of transfer wheel 45 will swing article 5from feed conveyor I9 through an arc toward the conveyor chain I5, asshown in Fig. 12.

The previous steps describe the beginning of the article transferprocess as relating to an empty machine first being loaded. Articles Awill be alternately picked up from the feed conveyors I9 and 20 in theorder 1, 2, 3, 4, 5, 6, etc. and will be placed before the lugs I8 onconveyor chain I5 in the same order. The conveyor chain I5 travels tothe right and carries articles A in the order 2, 1, 4, 3, 6, 5, etc.,reading from right to left, whereby articles from the conveyors I9 and29 will be positioned alternately in the conveyor I5. Articles aretransferred by first transferring the first article from conveyor I9 toconveyor I5, and then transferring the first article on the conveyor 20to the conveyor I5, the transferring being alternately from one conveyorand then the other alternately and con-, tinuously.

Package conveyor chain 7 The articles from the conveyors I9 and 20 aretransferred by the wheels 45 and 46 and delivered to the conveyor I5where they are carried to the package conveyor 1 to be packaged bysuitable packaging mechanism (not shown). The package conveyor 7comprises a plurality of buckets 96, Figs. 2 and 3. These buckets 96 arehingedly connected together at their adjacent ends by means of sprocketchain links which are adapted to be engaged by the teeth on the sprocketwheel 8. The conveyor 1 is an endless conveyor and comprises a pluralityof hingedly connected buckets 96 which are cut away at their upper endsas indicated at 91, Fig. 3, to permit the lugs I8 of the conveyor I5 topass therethrough. The buckets 96 are supported by a conveyor support 98and are prevented from shifting lamrally by means of the in-turnedflanges 99, which extend inwardly from each side of the support 98, asclearly shown in Fig. 3. The articles, as they are discharged from theconveyor I5, are fed successively into the buckets 96 of the conveyorchain 1 and are then moved to proper position where the articles arepackaged in proper cartons. The buckets 96 of the conveyor chain 1 arespaced relatively close together so that the articles to be packagedwill be in proper position to be packaged by high speed packagingmachinery.

The invention provides new and novel means for picking up articlessuccessively from feed conveyors and depositing them alternately to asingle conveyor, the feed conveyors being angularly disposed withregards to the main conveyor IT. The articles A are fed by the feedconveyor to a position where they are in a contact with each other andare then placed on a conveyor which has carrying lugs spaced relativelyfar apart. The articles from the conveyor I5 are then collected togetherin relatively close proximity and fed to successive buckets of theconveyor I, the conveyor buckets carrying the ar ticles A through aseries of positions where they are packed in suitable cartons. Theinvention provides new and novel means of a relatively inexpensivenature for feeding articles to a predetermined position, thentransferring the articles to a continuously moving transfer wheel wherethey are transferred to a continuously operating endless conveyor. Thearticles are shifted or transferred in the proper sequence and in aproper position to be delivered to a conveyor of a package or cartoningmachine. The articles are maintained in a predetermined stationaryposition until a releasable holder releases them at the proper timeintervals. The transfer wheels are constructed, arranged, and driven sothat they attain variable speeds to allow for fast operation and at thesame time slow down at the picking up and discharging positions. Themachine of the invention is relatively simple in construction and may beeconomically manufactured.
